5 Types of Entrance in Darkroom SDMLR

• SINGLE DOOR SYSTEM • DOUBLE DOOR SYSTEM • MAZE TYPE ENTRANCE • LABYRINTH • ROTATING DOOR SYSTEM

used for for inspection and maintenance of the cassette And screens • Cleaning of work surfaces • Services of equipment

White lighting

White lighting consists of? - Preferably centrally placed

60W Tungsten, 30W Fluorescent

light from safe lamp directly falls onto the work surface. ex. Beehive safelight - Minimum distance of ___ from working surface Best for loading and unloading areas

Direct Safe Lighting - 1.2m

- Directs the light towards the celling which reflects light back into the room • Is intended to provide general illumination of the dark room • Suspended atleast __ m above the floor.

Indirect Safelight - 2.1m

the color of light produced by intensifying screen

Spectral Emission

range of light wavelength that a film can absorb.

Film Sensitivity

important to match in radiography to produce high quality images.

Spectral emission and film sensitivity

The process of matching the color sensitivity of the film to the color emission of the intensifying screen.

Spectral Matching

Use orthochromatic film, which is sensitive to ultraviolet, blue, and green light.

Rare earth screen

Use blue-sensitive film

Blue light emitting screen

Use green-sensitive film

Green light emitting screen

HOW DOES A SAFELIGHT WORK? • When white light is passed through colored filters, certain wavelength (or colors) are absorbed by the filters, whilst those wavelengths, which correspond to the color of the filters will be transmitted. • Making the correct selection safelight filter (matching the filter to the film), means choosing a filter, which will transmit a color to which the film is relatively unresponsive, whilst stopping all light to which the film is most sensitive.

Read

READ No safe lighting is completely safe, all films will become signifivantly fogged if exposed to safelights for long enough. • Are not perfect absorbers of the undesirable wavelength and, In truth all films have some sensitivity to all wavelengths. • This is because safelight filters. Thus, the Intensity of illumination and the film-handling time must be kept to minimum if significant fogging is not occur.

READ

NOTE: If the safelight is not safe, you should do one of the following to correct the problem: RRC

1. Replace the bulb with one of lower wattage • 2. Raise the safelight lamp higher from working surface • 3. Check the filter -may be cracked or broken

- The system that removes the used/waste water and solutions from processing tank? - All drainpipes/hose must be _____ towards their eventual outlet

- Drainage system - slopped
